Some applications of nanophotonics in biomedicine

Abstract

In this work, the optical and electronic properties of nanomaterials are discussed, its fundamental characteristics and its application in the design of devices and techniques for detection, imaging and therapy, especially in cancer problems, are analyzed. Some recent results obtained in our laboratory where we have been able to measure concentrations of the order of 10-22 moles of complexes of interest are discussed. We report the detection of residues in blood of medications of the order of 10-8 and 10-9 molar (M), which opens the way for drug monitoring with a focus on the implementation of a personalized medicine. We discuss results of therapy techniques with the use of nanomaterials that have allowed us to reduce cell viability below 10%. These results show that nanotechnology is changing the health paradigm to preventive medicine, personalized and available to everyone.
